    Hi Marcus,

    Thanks for the comments!

    It's a good question. I am hoping that by putting the fans on the far right hand side, away from the grinding mess and activity, they will not pull in gunk....

    Still too busy to spend much time on this. Here is how the mock-up currently looks from the outside. Botton fan blows air in and the top fan pulls air out:

    Instructions are in the manual. Have you got a copy?

    You remove the cover from the bottom, unscrew the hoses from the hydraulic pump, and then just pull the whole tank/pump assembly out. Have a...

    There is a part number and serial number stamped on the bottom. Ask seller for that. It is a good deal.

    Hi Andy,

    I think you can find many of the answers to your questions in the manual. For example regarding the oil guns:

    Hi Tien,



    That last photo caught my eye. I have never before seen a circuit board literally laid out on top of a schematic. It doesn't use space efficiently but it would sure be fun and easy...

    The FP2 looks like a good deal. It appears that the only significant thing which is missing is the Y axis lead screw and the bracket which attaches that to the headstock. Perhaps it was crashed in...

    I didn't like the first version of the cover and threw it in the trash. Now working on version 2. Basic idea is to enclose as much as possible. So on the grind side all that is going to be visible...

    You should have a wrench that's about 250mm/10 inches long and give it a solid tug with your arm and shoulder. Don't throw your entire body weight into it!



    That's also what I typically do as...

    I've used Kuhne+Nagel for international transport once (1800kg grinder from Switzerland to northern Germany). They were outstanding, from pickup, through customs clearance, to final delivery with a...

    You listed 3 cases above, but not my case (2/3 HP motor with 2 HP drive). Do you agree with JCByrd24 that this is OK?

    Hi Peter,

    Others here can answer your questions better than me. But there is one thing I am quite confident about. You describe how oil can make its way into the spindle via the key way slot and...

    John, one further thought. Is there any way that something could have "smacked" the hex shaft for the X axis table lock on the door side? That would transmit force through to the locking lever and...

    Block at the back is for two purposes. First, safety. Keeps you from pulling the long reach head off in the forward direction and dumping it in your lap. Second, needed to lock the long reach head...
  15. Can I use a 1.5kW or 2kW VFD for a 0.6kW load?

    I want to operate a small spindle motor (0.55 kW, 200 Hz, 230V) from my 230V 50Hz mains. So I need an inverter. Here in Germany there are good used ones available at low cost, but for 1.5kW (2HP). ...

    I spent a few minutes looking at possible fan locations. Remember that I intend to enclose everything within a cover.

    I first thought about having the fan as below. The airpath is shown with the...

    0.0003" per tooth seems too thin to me. I usually aim to make chips that are around 0.05mm = 0.002" thick. But feeds and speeds are not my thing, so could be that I am not doing things right.

    That's a nice machine. I suggest that you replace the Y handwheel with one similar to the X and Z handwheels (with a spinner handle). Otherwise it's very slow to crank Y over. If you post the...

    I'm going to add a pair of 12V computer fans, one to push cold air in near the bottom and one to suck hot air out at the top. Need to find locations that are well projected against splash. Will...

    I'm very happy with it, it's still in use and working nicely, and the slides and gearing of my machine are always well oiled. I typically give it a pump or two into each line at the start of an hour...

    I haven't said anything about this because it's been a few years since I have poked around there. But what I remember is the following. The locking shaft is hex. Over part of that...
